Fixed 6913075: EA identifies escape state incorrectly after 6895383 fix

EA incorrectly identifies escape state of an allocation passed
as call argument when the allocation's escape state is ArgEscape.
Because of the code change the ArgEscape state is not updated
to GlobalEscape which leads to incorrect elimination of locks.
Found during running jbb.
